ABSTRACT:
An apparatus for estimating the traffic demand value of elevators wherein the period of time of elevator operation is divided into a plurality of sections, the traffic demand value for each section is measured, and an estimated traffic demand value of a corresponding section is estimated on the basis of the measured value. A weight coefficient is provided in accordance with a result of the comparison between the estimated and measured demand values to prevent the estimated value from greatly differing from the actual traffic demand whereby the elevators can be accurately group-supervised as intended.
